LOCKING DEVICE.

Application filed December 20, 1920.

To all whom it may concern:

Be it known that we, ANDREW Bnvnnn, GAETANO Gnnco, and ALFRED G. RIzzoLo, citizens of the United States, and residents of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Looking Devices, of which the following is a specification.

This invention relates to a locking device, and while it is applicable for many different purposes it is particularly designed for holding articles such as milk bottles, these being supported by the neck and can be readily inserted upon delivery, but can not be removed except after the device has been unlocked.

The invention is particularly designed for holding milk bottles and comprises members that swing to closed position so as to support the milk bottle at the top of the neck, the device, when emptygbeing easily opened by a latchoperated from the inside of the device, but when a milk bottle is held in place it prevents access to the latch and it is necessary to operate the latch from a'locking means which is normally held against movement by a key-operated lock.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a central vertical section of the device. Figure 2 is a back view thereof, partly broken away to show a part of the interior. Figure 3 is a top view showing the parts open. Figure 4: is a similar view showing the parts closed in looking position. Figure 5 is a view with the locking member removed'and several parts shown broken away and in section to more clearly illustrate the operation and the construction of the device, and Figure 6 is a detail perspective view showing the cooperation of the latch and the several. parts oi? the mechanism adjacent thereto. I

The device includes two holding members 10 and 11, these being preferably arranged in swinging relation, and one of them forms a. supporting member and has an extension which provides means for attaching it to a suitable support, such as a window or door casing .12. In the form shown this consists of a perforated back wall 13, through which the screws 14: are inserted, and being screwed on from the inside there is less chance of the device being removed.

oted, as at 15, and are normally swung apart by a spring 16 which is curved around the pivotal pin 15 so that the swinging member 11, when released, assumes the open position shown in Figure 3. "fhe members are provided with an open bottom 17, which is usually provided with a marginal flange 18 so that the bulged upper part 19 oi the neck of a bottle 20 acts to suspend the bottle when the holding members are closed, this being clearly seen from Figure 1.

To hold the holding members shut we provide a latch 21 which is hinged at 22 to the plate 23 which extends -from thetop part of the supporting member 10, the latch being normally held in its closed position by a small spring 24 which abuts at one end on a shoulder 25 on the plate 23, and at the other endon a small stud 26 projecting from the baclc ofthe latch. The member 11 has a means for engaging the latch so that the member 11. is held in its closed position, in the form shown this comprising a pin 27 arranged on a plate 28 which projects on the inside of the member 11, so that when the member 1.1 is swung around to its closed position the the spring 2411 causes the latch. to engage the pin 27 locked. I

Projecting downward :Froni the latch is a small fingei piece 29, as will be clearly seen from Figures 2 and 6. which projects downwardly a suflicient distance to provide means for operating the latch, which is readily possible when no element is being held by the device, since the open bottom gives free access in order that the delivery man can unlock the device to insert the bottle in position. After the bottle is in position, of: course this bottom being closed, the latch can not be operated from the inside.

To provide for its being secured against unlocking, and also to permit its being unand thus, hold the members locked, we arrange the locking member 30 which is pivoted, as at 31, to the plate 2 of the supporting member 10 and which has means for providing a key-operated lock thereto, this being preferably by means of c the short lever 32 which is in substantial alignment with the perforated projection 33 of the member 10, and the lever 32 being pertorated, the staple 34 of the lock 35 can be passed through these perforations to hold this locking member against swinging movemen-t.- The hub 36 of the locking member 30 is provided with a teeth 3! which is disposed so that itiengages the finger oi the latch 21 When the locking member is swung after the lock 85 has been removed therefrom. This permits the release of the bottle from the tWo holding members.

It Will thus be evident from this descrip tion that the latch 21 can be operated inde pendently of the locking member, as will be ,evident from ignre 2,,since the finger can be inserted for operating- 1t, but atter an artibe fitted together and having an open end that is closed when an element is locked therein, a locking member, a latch for looking the holding members together and operable by the locking member 'to'releasethe holding members, the latch having means thereonoperable from Within the casing by means of Which the holding memberscan be released ivhen no elementis locked therein. 2. A locking device comprising two me1nhers in swinging relation, a latch to "secure the members together, a locking means for the latch, the latch being operable from Within the casing so that it can be operated independent of the locking means.

3. A locking device comprising two hold;

1 ,aeaeea ing members in swinging relation, one of them having means for attaching it to a support so that it forms a supporting member,

a locking member pivoted on said supporting member and adapted to be locked againstpivoted movement, and a latch on said supporting member operable by the lockingvmember and also operable independ ent thereof, the swinging member having means for engagement With the latch, the holding members being open at the bottom so as to receive an article to be held therein, which article when in position prevents access to the latch. is V a. A locking device comprising two holding members in swinging relation, one of them having means for attaching it to a supportso that it forms a supporting member, a locking member pivoted to the supporting member, both thesnpporting member and the locking member having arms adapted to be placed approximately inalignment, whereby they can be locked to prevent the locking member from being. swung, a

latch on thesupporting;- member and adapted to be operated from the inside of the casing independent of the locking member, and (11% posed so as to bennlatched when the locking member is swung from its locked position, and means on the swinging member forengagement With the latch, the holding members being. open at the bottom so as to re ceive anarticle to be held therein, which article when in the latch.
